TOOL-HANDLE.

Application filed October 13, 1911.

To aZZ whom it may concern Be it known that I, EDWARD J. RENKEN- BERGER, citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Tool-Handles, of which the following is a specification.

This invention relates to tool handles and has for its object to provide a handle so reinforced as not to be liable to split.

The invention also has as its object to reinforce a wooden tool handle in such manner that no considerable area of the metallic reinforcing means will be exposed for contact with the hand of the user of the tool.

A further aim of the invention is to reinforce a wooden tool handle'throughout the entire .length of its tang-receiving portion without exposing any considerable area of the metallic reinforcing means to the hands of the user of the tool and without employment of but a minimum amount of the material for this purpose.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective view of the tool handle embodying the present invention. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical longitudinal sectional view in detail. Fig. 4 is an end view. Fig. 5 is a detail view partly in elevation and partly in section showing the manner of securing one end of the wire.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

In the drawing, the handle proper is indicated by the numeral 1 and is reduced at one end as at 2, this reduction in the diameter of the handle resulting in the formation of a shoulder 3 near its tang-receiving end. A spiral groove 4 is formed in the handle and terminates at one end in the shoulder 3 and enters at its other end into a groove 5 which circumscribes the handle at a point more or less remote from the tangreceiving end thereof, the line of extent of this groove 5 being a circle. The handle 1 is formed axially with a tang-receiving socket 6 at-its tang-receiving end with a number of gains 7 which extend radially from the said socket 6 and may be of any desired number.

Serial No. 654,542.

The means for reinforcing the handle 1 conslsts of a length of wire which is wrapped a greater or less number of times around the reduced portion 2 of the handle and at this end is bent substantially at right angles as at 8 and has its extremity opened and also bent at an angle as at 9, the portions 8 and 9 belng driven or otherwise embedded in the handle 1 at the said reduced portion thereof. The length of wire is then wrapped about the handle 1 in the groove 4 as indicated by the numeral 10 and in the groove 5, one or more times, as indicated by the numeral 11. The opposite end of the wire is bent at right angles at 12 and has its said portion sharply pointed and driven into the material of the handle as clearly shown in Fig. 2 of the drawing. After the wire has been thus wrapped about the handle, solder 1s applled upon several of the wrappings about the reduced portion 2, to form a band 13 and a drop of solder 14 is applied to the end 12 of the wire and the adjacent wrapping of the wire.

From the foregoing it will be readily understood that the wrappings about the reduced portion of the handle constitute a ferrule for the handle and that the portion of the wire which is wrapped around the handle in the grooves 4 and 5 serves to strengthen the handle and prevent its splittlng.

From inspection of Fig. 1 it will be observed that the first described end of the wire is embedded in the handle at a point between two of the gains 7 so that should the tang of a tool be so forcibly driven into the handle as to cause the same to split, the split will occur in a line with one or more of the gains and not at the point of the embedding of the end of the wire in the handle.

It will also be noted that due to the fact that the wire throughout the greater length of the handle is wrapped thereabout in the grooves 4 and 5 and lies below the surface of the handle, no considerable area of metal will be exposed for contact with the hands of the user of the tool and consequently all of the advantages of a wooden handle are secured and the handle is practically as durable as a metallic handle. Furthermore, where the handle is employed in connection with a soldering iron, for example, it will not become uncomfortably heated, due to the fact that the portion of the wire which is wrapped in the grooves 4c and 5 is not capable of conducting any appreciable amount of the heat to which the tangreceiving end of the handle is subjected. It will be readily apparent that the handle may be square, circular, oval, or in fact of any cross-sectional shape.

Having thus described the invention what is claimed as new is 1. A handle having a reduced end with a shoulder at one terminal thereof and formed with a spiral groove intersecting the reduced end at an angle to said shoulder and mergingat its other end into a substantially circular groove encircling the handle, and a wire embedded at one end in the reduced portion of the handle and wrapped in relatively close coils around such end from the extremity thereof to said shoulder to form a ferrule and traversing said spiral groove in spaced convolutions, and lying Within said circular groove in relatively close relation to the adjoining spiral of the wire, and at such end embedded in the wood, and means uniting the adjoining windings of the wire at opposite ends of the winding.

2. A handle having a reduced end With a shoulder at one terminal thereof and formed with a spiral groove leading from said 30 shoulder, and a Wire embedded at one end in the reduced portion of the handle and wrapped in relatively close coils around such end from the extremity thereof toward and abutting said shoulder to form a ferrule and traversing said spiral groove in spaced con volutions and at its terminal embedded in the handle.

In testimony whereof, I afiiX my signature in presence of two witnesses.
